Physics of Cosmic Acceleration

Submitted by Web Services Editor on Tue, 04/01/2014 - 14:50

The physics underlying the accelerated expansion of the universe is unknown. Most of my recent research aims to explore various explanations. Examples include: a dynamical scalar field, quintessence; new gravitational phenomena; and alternative scenarios that dispense with dark energy altogether. My students and I develop these ideas, to make predictions for comparison with observations and experiments.

Diversity and inclusivity are necessary partners. Without inclusivity, the benefits of diversity— an increase in understanding, improvement in performance, enhanced innovation, and heightened levels of satisfaction—will not be realized. We commit to investments in both, to create a community in which difference is valued, where each individual’s identity and contributions are treated with respect, and where differences lead to a strengthened identity for all.
